ATTACHMENT FOR INCANDESCENT GAS-BURNERS.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed June 12, 1912. Serial No. 703,280.

To all whom it may concern:

Be it known that I, MICHELE GIORGIO, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Incandescent Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to attachments for incandescent gas burners, and has for its object to construct a device operable to cut off the supply of gas should the same become extinguished accidentally, thus obviating the danger of accidents due to gas escaping from unlighted gas burners.

With these and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:-

Figure 1 is a partial sectional View of the invention showing the same in use in connection with an inverted burner. Fig. 2 is a side elevation of the same. Fig. 3 is a fragmentary sectional view of the valve and disk.

In the present embodiment of the invention there is disclosed a supply pipe 1, the flow through which is controlled by a valve 2. At the end of this pipe is an elbow 3 and from this elbow extends a vertical nipple 4 across the top of which is positioned a diaphragm 5 having a central opening 5 therein. Screwed to the nipple 4 is a goose neck 23 which carries on its free end a mantle support 24. Within the free end of the goose neck is a tube 8 and spaced along said goose neck are guides 22 through which passes a rod 21 carrying at one end a valve 25 which is arranged, when seated, to close the opening 5. Thisvalve and rod 21 are moved by means of the pin 6 which passes through slots 9 in the goose neck and engages said rod 21, the outer ends of the pin being attached to a ring 7. Extending across the goose neck is a bar 18 and surrounding the rod 21 and having its lower end secured'to the bar 18 is a coil spring 20 the upper end of which is secured to the rod 21. This spring serves to seat the valve 25 under certain conditions now to be explained. At the other end of the rod 21 is a hemispherical member 17 which is adapted, when expanded by the heat of the burning to grip the inside of the tube 8 so that the valve 25 is heldopen. If, however, the gas goes out, the spring 20 shuts the valve 25, the rod 21 being free to move by reason of the contraction of the member 17 leaving said member free to move in the tube 8.

There has thus been provided a simple and efiicient device of the kind described and of the character specified.

WVhat is claimed is The combination with a gas burner for inverted gas mantles and having a goose neck tube; a flexible rod extending along said tube, guides within the tube arranged to cause the rod to follow the curvature of the tube when moved therein, a ring encircling the tube adjacent one end, means for connecting the rod to the ring, a hemispherical member secured to the other end of the rod and adapted to hold the same in its raised position when the member is expanded by the heat of the burner, said hemispherical member being hollow, avalve carried by the first mentioned end of the rod, an apertured disk mounted in the tube and adapted to coact with said valve when the light of the burner is extinguished, and the member contracts.

In testimony whereof, I aflix my signature, in presence of two witnesses.
